Disclosed are various embodiments for navigating a taxonomy using search queries. An unstructured search query is parsed in order to identify one or more categories of a taxonomy of a collection of items. Each one of the one or more categories is associated with a confidence score. When the confidence score meets a threshold, a pool of items is selected from a respective one of the one or more categories. When no confidence score meets the threshold, the pool of items is selected from the collection of items.

Navigating a taxonomy using search queries

Disclosed are various embodiments for generating search results when a search string fails to return results as entered. In a representative example, a failure of a first query generated from a search string to identify at least a predefined threshold number of items from among a plurality of items in a data store is detected in a computing device. A plurality of altered versions of the search string is generated in the computing device. A submission of a plurality of second queries to the data store is implemented, where each of the second queries corresponds to one of the altered versions of the search string. A presentation is generated to be rendered of at least two separate groups of items resulting from corresponding ones of the second queries.

Implementation of a search for items

A collection of items may be categorized according to a category hierarchy. A search of the items may be explicitly associated with a particular category in the hierarchy or else unassociated. A set of refinements may be available, for example, to help narrow the search. Refinements may be applicable to items in linked categories. Refinements may be surfaced based at least in part on linked categories associated with the search. Refinements may be surfaced when the search is unassociated with a particular category. For example, a possibly relevant set of categories may be determined. Refinements may be surfaced according to a variety of ordering criteria.

Refinement surfacing for search hierarchies

Disclosed are various embodiments providing navigational aids within item search results. A pool of items is generated in a computing resource in response to a search query and a search context. At least one network page is encoded for rendering by a client. The at least one network page includes a ranked list of at least a portion of the items. The ranked list includes a navigational aid when a relevance score associated with the navigational aid meets a threshold. The relevance score is computed relative to respective relevance scores associated with items in the ranked list. The navigational aid has at least a same prominence within the ranked list as an item.
